My buddy Barry also loves his K52s, when I asked him to try my AKG-40s he said 'yeah they sound about the same to me' .. so I got that going for me.
Point is, sometimes more $$ doesn't equal what you were aiming for.
Find what works for you and use it.

I find myself working in headphones quite often, hasn't really bothered me bu I do notice speakers (especially nearfields) seem to make you 'feel' it a little more, not sure how to describe it except to say your whole body 'hears' it, not just your ears.
But I do not judge anyone one way or the other; do what works for you.

I do not work here, but the benefits are still awesome
Make your sound your own!
